ELECTRICAL CHARACTERISTICS

VCC = Full range, TA = -40ºC to +85ºC unless otherwise noted. Typical values at TA = +25ºC and VCC = 5V for

L/M/J versions, VCC = 3.3V for T/S versions, VCC = 3V for R version and VCC = 2.5V for Z version.

(continued)

notes:

() Production testing done at TA = +25ºC; limits over temperature guaranteed by design only.

(2) RESET output for the CAT809; RESET output for the CAT810.
